Reddit reviews Boye 5-Inch Steel Crochet Hook, Size 12

I vote no on the latch hooks. Most of them are rounded at the tip and too wide. Dreadheadhq has a pointy one that's ok. I bought one years ago and still have it around but never use it. With young, loose dreads, it works great. But once they're nice and tight even the pointy latch hook is too thick to push through. I prefer to use an upholstery needle like this. The medium sized one on the left. I use this with a piece of thread for pulling in loosies near the roots. Here's a tutorial on how I do it. She starts the "sewing" part at 2:00. It's pretty much the same concept as a latch hook, except it's much thinner and pushes through without loosening/weakening the dreads.

For loosies further down, I pull them in with a size 12 crochet hook. Well, I used to. After my dreads reached about 5 years old and were obviously done tightening up, I shaved up and down the length of them with electric sheers. 10/10 would do again! But I won't have to, since they're fully locked, nothing is going to slip out any more.
